Abstract

The aim of this study was to compare two different techniques for distalizing the mandibular dentition in patients with Class III malocclusion using either miniscrews or miniplates. We evaluated the skeletal and dento-alveolar changes associated with each method. The study also aimed at identifying cephalometric characteristics in the subjects associated with the most predictable, successful outcome of treatment. Patients and Methods: Our sample consisted of 20 adult subjects (10 females and 10 males) that met the inclusion criteria. We examined pre and post treatment headfilms and analyzed the dental and skeletal changes using a computer program that provided the data for statistical analysis (TIOPS4). Results: On average, both types of mechanics were successful in distalizing the lower dentition as seen by both the horizontal movement of incisors, premolars and molars and the changes in inclination of these teeth. A modest amount of vertical movement of incisors, premolars, and molars was observed in both groups, with the miniplates exhibiting slightly more vertical movement. When comparing the two types of anchorage, only the vertical level of the premolars and molars was statistically significant between the two groups with miniplates leading to more vertical change. Conclusion: Mild to moderate Class III malocclusions can successfully be treated with distalization of the lower dentition using either one of two mechanics (miniscrews or miniplates) as skeletal anchorage in the lower jaw.
